Sproket 15 Teeth 1/8 Bore

This little sprocket was the perfect fit for my robotics project, the self-lubricating material makes it run smoothly without any extra oil. My mechanism is quieter than it's ever been and it took just minutes to install.

The teeth mesh perfectly with my chain links—zero slop or binding once I got the bore aligned. The self-lubricating acetal resin means it spins freely without me having to oil anything, which is a huge plus for a closed gearbox.

Installed this on my robotics project and was surprised by how smoothly it runs—the self-lubricating material really does reduce friction. Also held up well during a three-hour test session without any visible wear. Exactly what I needed for reliable miniature mechanisms.
